SINEAD O'CONNOR has offered to become troubled pop star Britney Spears' "bodyguard". The Irish singer-turned-nun gave Spears a little unlikely support at a show in Los Angeles on Tuesday (18Sep07) when she dedicated her version of spiritual Rivers of Babylon to the struggling mum of two. O'Connor told fans, "I've been keeping an eye on a girl who is getting a hard time in the media lately, and I just want her to know that if she needs a bodyguard, I'm her girl. "I'd like to dedicate this song to Britney Spears."
